As the pans travel toward the left through themachine, as indicated in Figure I, the cleansing brush 20 rotates in the direction indicated by the arrow in Figure I, in consequence of which the bread crumbs and other foreign substance upon the pans are loosened and disengaged therefrom and are drawn outward through the exhaust pipe 30. In order to still further facilitate the cleansing of the pans, we have provided a pipe 35, which is in communication with a source (not shown) of air under pressure, and by means of which a strong blast of air can be directed against the said pans through small openings in the said pipe.

The mechanism thus far described is not novel with us, and we do not claim the same separately. Our invention relates specifically to improvements in the mechanism for greasing the pans, and the combination of the same with the other parts of the apparatus. The greasing mechanism comprises a grease-holding receptacle 40, supported upon posts 41, which are in turn supported upon brackets 42 provided on opposite sides of the appara tus. The receptacle extends transversely of the length of the machine and is of a length substantially equal to the width of the pans to be greased.

The grease or oil receptacle is provided with hollow spaces 43 in its side and end walls, which are adapted to receive steam or a similar heated substance (from a source not shown), the purpose being to keep the oil in a fluid or liquid condition. It will be understood that if the receptacle is allowed to become cold, the oil or grease becomes more or less firm and immobile and will not operate in the manner desired.

The lower side of the receptacle is closed by means of the strip 45 extending from end to end of the receptacle, and the said strip is provided with the plugs 46 at intervals, the said plugs respectively being provided with perforations or passageways 47 and 48, to permit the escape of the grease or oil in a vaporized state. These plugs may be designated as vaporizing nozzles.

49 designates caps which have screw-threaded connection with the lower end of the plugs 46. The ends of the said-plugs do not extend entirely to the bottom of the said caps, in consequence of which there is more or less space left in the caps between the bottom thereof and the lower ends of the plugs. The lower end of each of the caps is provided with a perforation 50 for the escape of the oil or grease from the receptacle 40.

The perforations 47 are in communication with the bottom portion of the receptacle and the oil or grease passes from the said receptacle through the said perforations. The

upper end of the perforations 48 is closed by means of a tube or pipe 51 which extends upwardly through the oil to a point somewhat above the upper level of the oil in the receptacle, as is clearly indicated in Figures III and IV of the drawings.

52 designates a pipe or tube communicating through the top of the grease or oil receptacle with the interior of the said receptacle for the purpose of conveying to said interior air or other suitable gaseous substance under pressure from a source of supply not shown.

It will be understood that the oil or grease should be permitted to escape from the receptacle 40 only when a pan is underneath the same.

In order to prevent the passage of oil or grease from the receptacle through the perforations 47 in the plugs 46. we have provided valves 55 for the purposeof closing and opening the said perforations 47. These valves also close and open the perforations 48. These valves extend through the plugs 46 and are provided with perforations (shown in Figure IV) which are adapted to be moved into and out of alinement with the perforations 47 and 48 in the plugs 46.

The first valve of the series, as shown in Figure III, is provided with a bell crank lever, one arm 56 of which extends or lies in a substantially horizontal position, while the other arm 57 extends downwardly. The remaining valves of the series are provided with levers 58. The levers 58 and the lever 57 are all connected at their lower ends to a rod or bar 59 extending across the machine, as clearly shown in Figure III.

WVhen a pan is underneath the grease or oil receptacle and the valves 55 are open, the levers 57 and 58 occupy a position somewhat to one side of vertical lines or planes through the respective valves, but when in their normal position, the said levers occupy substantiallv vertical lines or planes.

Vhen the valves 55 are in open position,

the oil or grease escapes through the perforations 47 in the plugs 46, the amount of the flow of oil or grease being increased by the pressure of air or other gaseous fluid on the top of the said oil or grease. The air also escapes through the pipes 51 and the perforations 48, and becomes mingled with the oil in the spaces between the bottoms of the caps and the lower ends of the plugs 46. The opening and the closing of the valves is effected automatically by the passage of the pans through the machine. As the pans pass through the machine the opposite edges thereof engage upon one side of the rotatable wheel 60 mounted upon a stationary bracket 61. The other sides of the said pans engage a rotatable wheel 62 mounted upon an arm or lever 68 carried upon and rigidly secured to a rotatable shaft 64 journaled in bearings 65 in the brackets 42. The brackets 61 and 42 are illustrated as being secured to and supported upon the side pieces 3 of the frame of the machine or apparatus, but, obviously they may be supported in any other suitable manner.

66 designates an arm or lever also secured to the shaft 64:, and in connection with the arm or lever 63 constitutes a bell crank lever. 67 designates a link connecting the outer end of the lever 66 with the outer end of the arm 56 of the bell crank lever secured to the [irst of the series of valves 55.

.ln order to hold the arm 63, lever 66, and the parts connected to the latter, in position to close the valves 55 when there is no pan in engagement with the contact roller 62, we have provided the coiled contractile spring 68 which is connected at one end to the frame of the machine and at its other end to one end of a projecting pin 69, the other end of which is connected to the arm 63.

The projecting pin 69, however, may be connected to the shaft 64 at any other convenient and suitable point. \Vhen a pan is ')assing through the machine and is in contact with the rollers and 62, the latter is moved outwardly against the pressure or tension of the spring 68 to open the valve, and as soon as the panescapes from the machine, the said contact roller 62, the arm 66 and the parts connected thereto return under the influence of the said spring to their normal position to close the valves and step further [low or escape of the oil from the receptacle.
